What’s different? The 5 differences that matter most, from the published figures.
- S140 Lawn Tractor weighs 212.3 kg (468 lbs); GR2120-48 weighs 440 kg (970 lbs), a 227.7 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What S140 Lawn Tractor's weight means for a trailer ›
- S140 Lawn Tractor holds 9.1 L (2.4 gal) of fuel; GR2120-48 holds 18 L (4.8 gal) of fuel, a 8.9 L difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
- S140 Lawn Tractor has a TLT200 hydrostatic, two-wheel drive transmission; GR2120-48 has a HST, Shaft Drive transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- S140 Lawn Tractor has a 22 hp engine; GR2120-48 has a 17 hp engine, a 5 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- S140 Lawn Tractor has Single belt drive; GR2120-48 has 4 w/Cruise control drive.
